AP Biology Without Previous Biology?

Hey, everyone. Just wondering if anyone can give me insight on AP Bio. I’ll be taking the course next year, but I haven’t had any previous experience with biology (no honors or regular biology class). That said, I’m a bit concerned and am wondering if anyone has gone through the same situation and achieved a 3 or a 4. I’m also wondering if anyone can recommend a concise review on honors biology that I can do over the summer. Thanks!

@cjjc256 I did a shorter online Biology course, but I know some people who have gone straight into AP Bio.
For learning Bio 1 over the summer, I recommend Barron’s E-Z Biology.
